control proportion situation; 2) Turn on the existing battery powered street lighting all the way, just one-sided Street strategy all the way on the street; 3) In the middle of the company's strategy of turning on the lights at night, the lights had to be turned off, and the existing battery power was only used for lighting. In terms of energy, solar street lamps are based on solar energy developed by new technology. With the continuous development of the times, green energy-saving and environmental protection products have attracted more and more attention, and vigorously developing green economy has become a trend today. Solar street lamps use solar radiation as energy. In order to ensure beauty and better receive solar radiation, please clean the dust on the battery module every six months, but do not wash it with water from bottom to top. So what are the benefits of installing solar street lamps for us? The following solar street lamp manufacturers will tell you: solar street lamps save electricity, which is used for solar energy. The solar power generation system converts solar energy into electric energy, which can alleviate the tension of energy utilization

the stock of street lamps ranges from 28million to 30million. In recent years, the number of new street lamps is 15% - 20%, about 3million-6million. According to the number of new street lamps each year, all of which are led lamps, the annual increment is 3-6 billion yuan. The failure rate of LED street lamps used for more than 6000 hours is less than 1%. Lighting accounts for about 19% of the world's electricity consumption. If the efficiency of the lighting system used in the world is twice that of the existing one, it can be said that it is equivalent to removing half of Europe's electricity consumption and heat emission. Recently, a global independent test has been established, and LED street lamps can save 85% of energy. In December 2011, China produced 250million sets of lamps and lighting devices, with a year-on-year increase of 12.45%. In 2011, the output of lamps and lighting devices nationwide reached 2.5 billion sets, with a year-on-year increase of 6.38%. In terms of the output of various provinces and cities, in 2011, the output of lamps and lighting devices in Zhejiang Province reached 1.07 billion sets, with a year-on-year increase of 9.13%, accounting for 42.40% of the total output of the country; The output of lamps and lighting devices in Guangdong Province reached 870million sets, a year-on-year decrease of 4.44%, accounting for 34.43% of the total output of the country. In 2011, the LED market will grow from US $4.7 billion in 2010 to US $5.8 billion, an increase of 23%. LED has become a popular product for manufacturing, and it is very easy to cause car accidents. It is a very attractive investment field. In addition, government support for the industry seems to be having an effect. It is estimated that the LED market will reach US $6.9 billion in 2012 and US $11.1 billion in 2015, with an annual compound annual growth rate of 17.7%. The construction of street lamps in China has achieved rapid development. The lighting quality of the impact sample V-shaped and U-shaped notch standard sample drawings on the road and projection screen has been continuously improved. High intensity gas discharge lamps have been widely used, which has played a great role in improving China's investment environment, promoting rapid economic development, facilitating people's life, beautifying the city and building an export-oriented modern city. Therefore, efficiency is the fundamental factor that determines the service life of the power supply. The efficiency should not be too low, otherwise the heat consumed in the power supply is too large. The efficiency of non isolated type is higher than that of isolated type, which is generally more than 80%. However, the efficiency is related to the matching connection of the lamp board. 9. The main factor of the LED street lamp light source heat dissipation scheme is that the LED street lamp beads can greatly prolong the service life under the condition of not overheating. If it is to be used for driving, it can be completed by using multiple PIR sensors and LDR sensors for faster vehicles. But now it is mainly for human body sensors, not for the sensors used by vehicles. For human body sensing solar street lamps, the sensing distance of sensors can be selected according to the installation interval of solar street lamps

the main principle of solar power generation is the photoelectric effect of semiconductors. Silicon atoms have four electrons. If pure silicon is doped with atoms with five electrons, such as phosphorus atoms, it becomes a negatively charged n-type semiconductor; If pure silicon is doped with atoms with three electrons, such as boron atoms, a positively charged p-type semiconductor is formed. Solar LED street lamp design for road lighting system design, we generally need to consider the following factors: from the function of solar street lamp, the main function of road lighting system is to ensure traffic, improve traffic efficiency, protect people, provide a comfortable environment, and improve the image of the company. On the basis of meeting the functional needs of road lighting, improve the energy efficiency of road lighting system, reduce system power consumption, save energy and reduce pollution, so as to achieve the purpose of energy conservation and environmental protection. In addition, it is also necessary to integrate the actual situation of local sunshine resources without complaint, local normal continuous overcast and rainy weather conditions, battery panels covered by dust, temperature effects, various efficiencies of controllers and batteries, etc
